More Information
Summary:The present application discloses a sintered ceramic material, a powder composition for obtaining the same, a manufacturing process and ceramic pieces thereof, and specifically discloses a sintered ceramic material having high fracture toughness and bending strength, which is obtained from an yttria-stabilized Zirconia powder, a powder composition for obtaining the material, sintered ceramic pieces and manufacturing process thereof. One of the solutions of the present invention discloses a sintered ceramic material which is obtained from an yttria-stabilized zirconia powder, comprising between1.8 and 2.1 mol% yttria, wherein the sintered ceramic material has a percentage of tetragonal phase greater than 90% at room temperature, a grain size between 0.1 to 0.25 [mu]m, the bending strengthis between 1150-2100 MPa, and simultaneously a toughness greater than 10 MPa.m1/2. The material may be applied in different sintered ceramic pieces, including pieces for the automotive sector, for diverse machinery, ornamental
